Open framework materials as battery electrodes are drawing much more attention recently in view of the requirement on further improving energy storage and power densities, as well as use of a nonlithium cation (such as Na + and Mg 2+ ) transport. In this work, we show a novel top-down approach to prepare fluoride-base…
Graphene allows us to control light in innovative ways, providing the prospect of unprecedented nanophotonic devices.
A solution-processed diketopyrrolopyrrole (DPP)-based small molecule, namely BDT-DPP, with broad absorption and suitable energy levels has been synthesized. The widely used solvents of chloroform (CF) and o-dichlorobenzene (o-DCB) were used as the spin-coating solvent, respectively, and 1,8-diiodooctane (DIO) was used…
Nitrogen-doped ZnO bundle-like nanoparticles were prepared by heating ZnOHF precursor at different temperatures under an ammonia atmosphere. ZnOHF gradually transformed to N-ZnO with the increase of the heating temperature, and the as-prepared N-ZnO nanoparticles preserved the original morphologies of ZnOHF at moderat…
Unconventional superconductivity and other previously unknown phases of matter exist in the vicinity of a quantum critical point (QCP): a continuous phase change of matter at absolute zero. Intensive theoretical and experimental investigations on itinerant systems have shown that metallic ferromagnets tend to develop…
This paper addresses the use of ground granulated blast furnace slag (GGBS) and reactive magnesia (MgO) blends for soil stabilization, comparing them with GGBS-lime blends and Portland cement (PC) for enhanced technical performance. A range of tests were conducted to investigate the properties of stabilized soils, inc…
We report a novel quantum-dot-conjugated graphene, i.e., hybrid SiO2-coated quantum dots (HQDs)-conjugated graphene, for targeted cancer fluorescent imaging, tracking, and monitoring drug delivery, as well as cancer therapy. The hybrid SiO2 shells on the surface of QDs not only mitigate its toxicity, but also protect…
Titanium and titanium alloy implants that have been demonstrated to be more biocompatible than other metallic implant materials, such as Co-Cr alloys and stainless steels, must also be accepted by bone cells, bonding with and growing on them to prevent loosening. Highly ordered nanoporous arrays of titanium dioxide th…
We demonstrate that yellow luminescence often observed in both carbon-doped and pristine GaN is the result of electronic transitions via the ${\mathrm{C}}_{\mathrm{N}}\mathrm{\text{\ensuremath{-}}}{\mathrm{O}}_{\mathrm{N}}$ complex. In contrast to common isolated defects, the ${\mathrm{C}}_{\mathrm{N}}\mathrm{\text{\e…
A new photothermal coupling agent for photothermal ablation (PTA) therapy of tumors is developed based on ultrathin PEGylated W18O49 nanowires. After being injected with the nanowire solution, the in vivo tumors exhibit a rapid temperature rise to 50.0 ± 0.5 °C upon irradiation with NIR laser light at a safe, low inte…
Hybrid anode materials for Li-ion batteries are fabricated by binding SnO2 nanocrystals (NCs) in nitrogen-doped reduced graphene oxide (N-RGO) sheets by means of an in situ hydrazine monohydrate vapor reduction method. The SnO2NCs in the obtained SnO2NC@N-RGO hybrid material exhibit exceptionally high specific capacit…
Compensation effect of blue phase I (BP I) with blue phase II (BP II) liquid crystal was demonstrated. BP I and BP II were co-exist in the optoeletronic device by polymer stabilization. Consequently, disadvantages of BP I and BP II were greatly improved by compensation effect and resulted in high contrast ratio, low h…
Among electromagnetic spectrum, terahertz region has been utilized less due to the lack of appropriate devices that works well in these frequencies But recently growing interest has been focused to design devices with functionality in terahertz region because of potential terahertz applications. We present a novel str…

We report the results of first-principles calculations for the atomic, electronic, and magnetic properties of the Co atoms embedded in divacancy defects in graphene nanoribbons with zigzag-shaped edges. We find that the edges play an important role in the stabilization of a Co-divacancy complex near the edge, where th…
In this work, the first generation of poly(propyleneimine) dendrimers were functionalized with alkoxysilane terminal groups and subjected to one of two different sol-gel process that followed two different catalytic pathways, that is base- or acid-catalyzed pathways. Thus, two series of new organic-inorganic hybrid ma…
A set of terfluorenes and terfluorene-like molecules with different pendant substitutions or side groups were designed and synthesized, their photophysical properties and the excited-state geometries were studied. Dual fluorescence emissions were observed in compounds with rigid pendant groups bearing electron-donatin…
The structural, energetic and electronic properties of carbon nanobuds (CNBs) with the smallest fullerene C 20 covalently attached to the sidewall of single-walled carbon nanotubes (SWNTs) are studied by first-principles calculations. Due to the high curvature of C 20 and the resulting chemical activity, the binding b…
Les britholites ont suscité un grand intérêt auprès des chercheurs en raison de leurs applications potentielles en tant que matrices pour le confinement de certains déchets séparés issus de l’industrie nucléaire, comme les actinides mineurs et certains produits de fission. Cependant, leur préparation nécessite des tem…
Purpose – Steel heavy plates, grade S355, micro‐alloyed with Vanadium‐V and/or Niobium‐Nb plus Titanium‐Ti in thicknesses from 5 to 60 mm, 200.000‐350.000 t/y, are produced according to EN 10025 at STOMANA S.A., a company of the SIDENOR Group in Pernik Bulgaria, and are exported to the European Market.
